I spent about a year arguing with C-levels that our fleet running 8GB was slowing down productivity, with evidence to prove it. It was like pulling teeth to procure some SODIMMs.
I’d still say this article is coming at things from the wrong perspective. That $700 Walmart M1 MBA is more than adequate for most kids doing school work, and/or grandparents farting around on FB. If you have a family and had to grab a few identical laptops, and you aren’t able/willing to be tech support, it really makes a lot of sense financially.
If you were just going to use it for browsing the web then you don't need anything that's capable as an M1 processor, you're just paying for performance overhead. Just buy a cheap Lenovo. Yeah I know we don't like Windows but it's a well-known operating system and when it inevitably breaks you don't have to go to Apple to fix it. Any random PC repair shop will be able to deal with it.
